Hello,
Our VSMS keeps unmounting the VSAN media's giving this error:
Log I/O Error Detected

Ouch!
Unfortunately, this isn't really an issue with VSM at all, but likely a problem with the VSAN itself. It's the Linux kernel informing you of the I/O error (which then triggers it to unmount the filesystem). My advice would be to engage the support of the SAN vendor to help troubleshoot why you are experiencing I/O problems.

Even if it's just to bounce ideas around, let me know.
Cheers!

An absolutely *wild* stab in the dark actually... the message seems to indicate the (journal?) logging for the filesystem on top of the block device? I know a lot of logging systems are quite picky about write caching, so perhaps it's something to do with that? :-S
